Abstract
Abstract The present invention relates to a process for the preparation of a "self-degrading" composition suitable for use in feeding and/or feed-conversing purposes and if desired for the conversion thereof into a self-degrading fodder mixture which comprises pre-degrading the starch being present in cereal fodder and/or maize fodder to an extent that the degradation index of the crop should be from 0.12 to 0.27, and thereafter admixing the so-called "available starch" thus obtained in finely ground form in optional order of succession with α-amylase and optionally with further additives and--if "self-degrading" fodder mixture is to be prepared--with fodder. The composition of the present invention provides carbohydrates utilizable by the digestive organs of animals. The process of the invention provides products equivalent with the very expensive maltodextrins using cheap and readily available starting materials.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
89 words
A process for making a dry, self-degrading composition capable of activation in the presence of water and promoting the degradation of fodder substances, said process comprising: (a) heating an amylaceous cereal or maize to thermally predegrade it to a degradation index of 0.12 to 0.27 thereby converting it into solid, available starch; (b) grinding the solid, available starch formed in step (a) to a particle size of 50 to 1500μ; and (c) admixing the ground, solid, available starch with finely divided powdered alpha-amylase to produce said dry self-degrading composition.
Claim 2
Dependent Claim
89 words
A process for making a dry, self-degrading composition capable of activation in the presence of water and promoting the degradation of fodder substances, said process comprising: (a) heating an amylaceous cereal or maize to thermally predegrade it to a degradation index of 0.12 to 0.27 thereby converting it into solid, available starch; (b) grinding the solid, available starch formed in step (a) to a particle size of 50 to 1500μ; and (c) admixing the ground, solid, available starch with finely divided powdered alpha-amylase to produce said dry self-degrading composition.
Claim 3
Dependent Claim
16 words
The process defined in claim 1, further comprising: (d) dry packing the composition of step (c).
Claim 4
Dependent Claim
44 words
The process defined in claim 1, step (a), which comprises predegrading the amylaceous cereal or maize by dry thermal or hydrothermal methods selected from the group consisting of infrared radiation, popping, heating and flocculation with the aid of steam, husking, expansion-extrusion, cold-rolling and explosion.
Claim 5
Dependent Claim
23 words
The process defined in claim 1, step (b), wherein the solid, available starch is ground to a particle size of 100 to 600μ.
Claim 6
Dependent Claim
58 words
The process defined in claim 1, step (c), which comprises using commercial alpha-amylase enzyme having an activity of 5,000 SKB/g in an amount of 0.1 to 2% by weight, related to the dry starch substance weight of the ground starch, or an enzyme having another activity in an amount equivalent thereto within the limits of the above interval.
Claim 7
Dependent Claim
33 words
The process defined in claim 1, further comprising: (e) adding a compound selected from the group consisting of calcium chloride, sodium chloride, calcium carbonate, a water-soluble hydrogen carbonate and a water-soluble hydrogen phosphate.
Claim 8
Dependent Claim
22 words
The process defined in claim 1, further comprising: (f) adding a salt or ozide of iron, manganese, copper, selenium, zinc or cobalt.
Claim 9
Dependent Claim
35 words
A process for the preparation of a degraded fodder substance which comprises mixing fodder with 5 to 85% by weight of the self-degrading composition defined in claim 1 base on the dry substance content thereof.
